retireditguy - My doctor recommended taking a small dosage erectile function medicine (I believe it was Cialis) for the first six months, so I did this for that amount of time - I am not a huge fan of prescription drugs, unless there are no other options. However, I did make sure to encourage erections at least once per day - My attitude post surgery was that if you don't use it, you lose it. Erectile function was not a primary goal, thus I did not do any professional rehabilitation, but my attitude was, why not do everything possible on my own to maintain all functions post surgery.

Erectile firmness took a while to come back, but slowly improved over the 18 month period. I am someone that has always had very firm erections while sleeping, so not sure how this impacted my recovery or differs from other men who have had radical prostatectomies. FYI - For several days following the prostate removal, I had full erections while sleeping, but then the erection firmness dissipated and took 18 months to come back.

Best of luck with your recovery and please let me know if you would like any additional detail or if I have not answered your questions fully.
